Transportation And Storage - CHINT NJG2 Operation Manual

Selection of varistor: The nominal operating voltage of the varistor should be
●
selected according to 1.8-2 times the effective value of the SSR's operating
voltage.
Products with an operating current below 5A should be installed near a heat
●
dissipation window with good ventilation, or where is exposed to the cooling wind.
Products with an operating current above 5A should be installed with a heatsink.
●
Thermal conductive silicone grease should be applied between the relay and
the heatsink to enhance heat dissipation. When the surface temperature of the
heatsink approaches 60°C, forced air cooling should be implemented.
In order to prevent the temperature rise of SSRs from exceeding the allowable
●
value, the heat dissipation effect and installation location should be fully
considered during design and application. When installing multiple SSRs side by
side, it is required to leave a suitable distance between them.
